Abstract
A multilayer ceramic capacitor that includes a laminated body having a plurality of ceramic layers including crystal grains that have a perovskite structure, and a plurality of internal electrode layers; and external electrodes on first and second end surfaces of the laminated body and electrically connected to respective sets of the plurality of internal electrodes. In the ceramic layers, when the content of Ti is 100 parts by mol, the ceramic layers contain Ca at 0.10 to 15.00 parts by mol; Mg at 0.0010 to 0.0097 parts by mol; R at 0.50 to 4.00 parts by mol; M at 0.10 to 2.00 parts by mol; and Si at 0.50 to 2.00 parts by mol, and core parts of the crystal grains contain Ca.
